The original Prestolite starters have to be rebuilt. I believe Arco makes a new version of the Delco starter. I also believe there is a pmgr (gear reduction) available. I will see if i still have the part numbers.

The problem I'm having is that when I try to start the starter will turn the engine very slowly then stop! I've had starter rebuilt, replaced starter relay, new batteries, removed and cleaned all battery cables! What's else can I check or replaced!

Check for water in the cylinders.Maybe Trying to hydrolock due to leaky intake,exhaust or head gasket.
